riefly compare and contrast how asymmetric cryptography

Please Can I get answers to this questions

Question 1: Briefly compare and contrast how asymmetric cryptography is used to provide encryption as opposed to how it can be used to provide a digital signature.

Question 2: What is the purpose of the Diffie-Hellman algorithm? What are its major strength(s) and weakness(es)?

Question 3: Using RSA, let p = 17, q = 13 and e = 5.  What are the complete public and private keys?

Question 4:  Briefly explain how steganography is implemented in order to hide a textual message within a photographic image

Question 5:  A foreign navy has implemented a secure communications system in which submarine commanders transmit a single 5-letter message every day. The messages may only use capital (English) letters, and all messages are equally probable.  A crypto device encrypts each message into 20 bits of ciphertext.

What is the entropy of the plaintext message?

What is the entropy of the ciphertext message?

Is this a good cryptosystem? Why or why not?
